Amgen announced that the US Court of Appeals for the Federal Circuit has affirmed the judgment of the US District Court for the District of New Jersey in a patent infringement lawsuit against Sandoz and Zydus Pharmaceuticals. The decision affirms the permanent injunction entered by the district court prohibiting Sandoz and Zydus from making, using, selling, offering to sell, or importing each of their generic versions of Otezla until February 2028.
Three of Amgen's patents were the subject of the appeal. The appellate court upheld the validity of U.S. Patent No. 7,427,638, which claims pharmaceutical compositions of apremilast, and U.S. Patent No. 7,893,101, which claims a crystalline form of apremilast, but ruled against Amgen on U.S. Patent No. 10,092,541, which claims methods of treating psoriasis with apremilast according to a specific dosing schedule. Before trial, both Sandoz and Zydus acknowledged that their generic versions of Otezla infringe the asserted claims of U.S. Patent No. 7,427,638.
In the U.S., Otezla is approved for the treatment of adult patients with plaque psoriasis who are candidates for phototherapy or systemic therapy, adult patients with active psoriatic arthritis and adult patients with oral ulcers associated with Behçet's Disease.
